Bought ours online from Home Depot. They had TONS to choose from.

Thank you

If anyone has any more suggestions, I would appreciate it. I need a narrow corbel. The panels only have a 2 5/8" gap between them. I found a set at van dykes, but they are discontinued. I'm looking for something with detail like a grape corbel or similar.

Try Hardware Resources.

This is one I found when Googling this trying to remember the other two I have used. This is called 'inviting home' and I have not used them or heard of them before. Worth checking out.

This is one of the ones I have used and has a great selection of styles and several sizes within the same style too. I've also used their moldings and other carved wooden pieces during my remodeling. They have a good selection and I believe are some of the originals I see copied elsewhere. They're called White River hardwoods. Below is a link to their corbel section ...

Try local antique stores! I found a PAIR of solid wood 1 1/2' very heavy corbels at a store that has a summer sale every year. They look to be Oak, but not sure of that. Anyway, giving a heads up in trying antique malls/stand alone stores/auctions.
